DETAILED DESCRIPTION

In one or more embodiments of the invention, a wearable wrist band or “bracelet” (collectively referred to as a band herein) is provided that includes a sensor for measuring heart rate, pulse, temperature, or the like and displaying an indication of the measured data such as (1) a color; and/or (2) a message, which may depend on the value of the measured data. Examples include, for example:

-   -   (1) a stress level band having a color and/or message based on a         measured stress level of a person wearing the band (e.g., as         determined by measuring and/or monitoring heart rate, pulse         rate, body temperature, perspiration, or the like); and/or     -   (2) a zone band having a color and/or message based on a         determined heart rate zone of a person wearing the band (e.g.,         recovery, fat burning, target heart rate, anaerobic zone,         maximum, etc.).         In some embodiments, the bands may be flexible and/or         waterproof. Such bands are simple to use and inexpensive.         Example embodiments are these and other bands are described         below.

FIG. 1A is a schematic diagram of a band 100 provided in accordance with the present invention. The band 100 may include a biometric sensor 102 coupled to a controller 104, and display 106 coupled to the controller 104. The band 100 may be fabricated from any suitable material. In some embodiments, the band 100 may be formed from a flexible and/or waterproof material such as silicone; and the sensor 102 and/or controller 104 may be embedded therein.

The sensor 102 may include any suitable biometric sensor configured to measure one or more of but is not limited to, heart rate, pulse rate, temperature, respiration, acceleration, skin resistivity, etc. More than one sensor 102 may be provided.

The controller 104 may include a programmable logic controller, microprocessor, application specific integrated circuit, or the like having suitable programming code for performing the methods described herein. More than one controller 104 may be used.

The display 106 may be any suitable display such as a liquid crystal display, electronic paper display, organic light-emitting diode display, or the like.

A battery 108 may be provided for powering sensor 102, controller 104 and/or display 106. In some embodiments, battery 108 may be rechargeable and/or replaceable. In one particular embodiment, the battery may be recharged via a USB connection (not shown) that allows information to be transferred from band 100 to another device such as a computer (not shown).

In some embodiments, the band 100 may configured to communicate wirelessly with other devices such as a mobile telephone, tablet computer, laptop computer, desktop computer or the like. For example, FIG. 1B illustrates an embodiment of the band 100 in which the band 100 includes communications device 110 such as a transmitter/receiver chip that allows the controller 104 to communicate with a mobile device 112. In some embodiments, the controller 104 may send information to and/or receive information from mobile device 112 using a wireless protocol such as WiFi, Bluetooth, or the like.

FIG. 2 is a flowchart of an example method 200 of employing the band 100 for zone training. With reference to FIGS. 1A-2, an exerciser (not shown) may wear the band 100 on his/her wrist. In step 201, sensor 102 of band 100 detects and measures the heart rate, pulse or another biometric parameter of the exerciser and provides this information to controller 104.

Based on the measured heart (or other information), in step 202, the controller 104 may determine an exercise zone for the exerciser. Generally, recommended exercise zones may depend on such factors as age and/or weight. In some embodiments, band 100 may be pre-programmed with particular definitions of the target heart rates for multiple zones. Any number of zones may be used (e.g., 1, 2, 3, 4, 5, 6, 7, etc.). For instance, bands may be pre-programmed with suitable heart rate zones for exercisers based on age and/or weight. In other embodiments, an exerciser may specify his/her age and/or weight and controller 104 may determine appropriate heart rate zones for the exerciser. For example, a mobile device 112 may include an application that prompts an exerciser for his/her age and/or weight, and then communicates this information (or zone information calculated by the mobile device) to the controller 104 via communications device 110.

In step 203, the band 100 displays heart rate zone information. For example, the controller 104 may cause display 106 to display a different color for each heart rate zone. In some embodiments, text information may be provided such as heart rate, zone, encouraging messages and/or warnings, or the like. Table 1 below provides exemplary colors for heart rate zones. Other colors may be employed.

TABLE 1 HEART RATE RANGE (BEATS PER MINUTE) COLOR 70-95 GREEN  95-105 BLUE 105-120 PURPLE 120-135 YELLOW 135-150 PINK 150+ RED

In at least one embodiment, the controller 104 may include exercise routines that specify which heart rate zones an exerciser should be in and/or move between during an exercise routine. Band 100 may display an up arrow or down arrow (or other indicators) to indicate that an exerciser should increase or decrease his/her heart rate so as to move to another zone. A zone band may have a color and/or message based on what zone a user's heart rate is in (e.g., recovery, fat burning, target heart rate, or anaerobic zone). A different color can correspond to each zone, and/or the band 100 may display the current zone as a message.

FIG. 3 is a flowchart of an example method 300 of employing the band 100 for monitoring stress level in accordance with the present invention. With reference to FIGS. 1A-1B and FIG. 3, a user (not shown) may wear the band 100 on his/her wrist. In step 301, sensor 102 of band 100 detects and measures the heart rate, pulse or other biometric parameter of the user and provides this information to controller 104.

Based on the measured heart rate (or other parameter such as temperature), in step 302, the controller 104 may determine a stress level of the user. In general, heart rate increases as stress level increases. As such, controller 104 may determine when the heart rate of the user rises above a pre-determined heart rate level (e.g., such as a steady state heart rate for the user, or a heart rate measured when the user is relaxed). Zones of stress may be determined for the user such as low stress, moderate stress, high stress and extreme stress based on various heart rate ranges of the user. Temperature of the user may be similarly employed (e.g., as temperature may decrease with stress). Such stress ranges may be pre-programmed, determined by the controller 104, determined by mobile device 112 and communicated to controller 104 or the like. For example, a mobile device 112 may include an application that prompts the user to meditate, breath deep or otherwise relax when determining a low stress level for the user. The mobile application may then communicates this information (or zone information calculated by the mobile device) to the controller 104 via communications device 110.

In step 303, the band 100 displays stress level information for the user. For example, the controller 104 may cause display 106 to display a different color for each stress level zone of the user. In some embodiments, text information may be included such as heart rate, stress level zone, encouraging messages and/or warnings, or the like. Table 2 below provides example colors for stress level zones. Other colors may be employed.

TABLE 2 STRESS LEVEL COLOR LOW GREEN MEDIUM BLUE HIGH PURPLE EXTREME RED

In at least one embodiment, the controller 104 may cause messages to be displayed on the display 106 such as “relax”, “breathe”, “getting agitated”, “step away from the situation”, or the like based on the level of stress of the user. In some embodiments, a stress level band may have a color and/or message based on stress level (e.g., as determined by heart rate, pulse, temperature, etc.). A user may use mind control to adjust your heart rate and change the message (e.g., via breathing techniques). Any suitable message may displayed such as be calm, back off, getting agitated, etc.

In some embodiments, the band 100 may be a “mood” band. For example, sensor 102 may measure temperature of a user and provide the temperature information to the controller 104. In response to this information, the controller 102 may cause display 106 to display a color representative of the user's mood. Example colors are provided below in Table 3. Other colors may be employed.

TABLE 3 MOOD COLOR HAPPY/PASSIONATE DARK BLUE CALM BLUE SLIGHTLY CALM BLUE GREEN NORMAL GREEN SLIGHTLY NERVOUS AMBER ANXIOUS GRAY STRESSED BLACK The temperature ranges used for each mood/color may be pre-selected based on statistical averages for men, women, boys, girls, etc., or in some embodiments, may be determined by the controller 104 by monitoring the steady state or normal temperature of a user and/or the temperature of the user during known times of stress. For example, mobile device 112 may include an application that asks a user his/her mood. Based on this information, the mobile device 112 may direct the controller 102 to store relevant temperature ranges which correlate to moods of the user. Of course, if desired, a mood band may be formed using thermotropic liquid crystals calibrated to a nominal temperature of about 82° F. as in a conventional mood ring in place of or in addition to the above described controller embodiment.

In some embodiments, the band 100 may be configured to detect the presence of like bands. For example, a band 100 a may be assigned to a group 400 of bands 100 a-d as shown in FIG. 4. Fewer or more bands may be in the group 400. Each band 100 a in the group 400 may be configured to communicate with other bands in the group 400 (e.g., via communications device 110 and/or mobile device 112) so as to identify members of the group, such as to beep, vibrate, change colors and/or display a message when other people/members of group 400 are near (e.g., other people from your college, people with similar interest or status, people within a frequent flyer program or points level, etc.), or the like. For instance, each band 100 a-d may periodically broadcast identifying information so that any band in the group 400 may detect and identify the band(s).

In some embodiments, bands 100 may “exchange” information with other bands in a group or any other band. For instance, the sensor 102 may include an accelerometer (not separately shown) that may recognize a handshake by a user of the band (e.g., by detecting the rapid up/down motion which occurs when two people shake hands). This may trigger the controller 104 in the band 100 of each person to share contact information for the user (e.g., email addresses, cellular telephone numbers, generate a Facebook friend request, or the like). Likewise, bands may be “bumped” together to share information. Any such information may be communicated to mobile devices 112 if desired. As an example, person A wearing band 100 a may shake hands, high five, bump fists, etc., with person B wearing band 100 b. Each band 100 a, 100 b may include a sensor 102 such as an accelerometer, strain gauge or the like which detects an acceleration and/or an acceleration pattern along one or more axis that is identifiable by controller 104 of each band 100 a, 100 b as a request to share information. In response thereto, controller 104 of each band 100 a, 100 b may cause information to be shared. For instance, bands 100 a, 100 b may directly broadcast information between one another; and/or bands 100 a, 100 b may direct mobile devices 112 of each user to share contact or other information.

In other embodiments, a wearable band may include a built in flash drive in place of or in addition to one or more the above. For example, monitored/collected data may be stored on the flash drive.

In one or more embodiments, a band may be used to motivate people to take the stairs. Most staircases in buildings are stark and depressing. A hotel chain may spruce of their staircases and even provide incentives for people to use them (to promote healthy living, save electricity by not using elevators, etc.). One or more of the above bands may be used as part of such a promotions.
